⻬ 16 Differential

Input Channels

⻬ Unity Gain Combines

with A/D Gains to
Provide Full Scale
Inputs from
±156 mV to ±10 V

⻬ Ultra Low-Noise,

High-Speed Design

The OMB-DBK85 provides
16 channels of differential
voltage input. It has a single,
unity-gain input stage on all
channels. When this is coupled
with the A/D’s on-board x1 through
x64 programmable input gains, full
scale input ranges from ±10 V down
to ±156 mV.

The OMB-DBK85’s ultra low noise,
high-speed design allows users to
expand their input to 256 channels
without sacrificing measurement
integrity.
